J. E. COOK FABRIC CUTTER Sept. 4, 1951 Filed April 1, 1948 INVEN7LOR. BY u/erame E. COOK iii/75 ATTORNEY Patented Sept. 4, 1951 UNITED STATES PATENT 0 F F I CE FABRIC CUTTER Jerome E.

1 Claim. 1

My invention relates to a cutter for pile fabrics and its principal object is to enable the operator to out a pile fabric from the back rapidly and accurately.

In the drawing, Fig. 1 is a side elevation, Fig. 2 is a sectional view on line 22 of Fig. l, and Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

The vertical plate 6 has a shallow recess 1 in which the cutting blade 13 is supported with its bottom edge resting on an abutment 9 which is a part of plate 6. The recess 1 has an outlet H for the discharge of foreign matter in the recess. The outlet also provides access to broken blades so that they can be pushed up for removal. The

cutting blade I3 is held in the recess with the lower cutting corner M of the blade extending down sufficiently to out through the back of the fabric. The plate 6 has a hole 8 in its upper part. The plate 6 extends forward closely in line with the blade l3 and thereby serves to aid the operator in maintaining the line of the cut and prevents the cutter from tipping up, if the blade should strike an obstacle, and disengaging the blade from the fabric.

A plate I0, permanently fixed to the plate 6 as by welding, covers the recess 1 except that it has a square hole l2 which registers with and is slightly larger than the hole 6. The plate ID has a recess ll so that the blade [3 may be bent and moved up by the operator in the recess 1, out of cutting position. The square hole in plate [0 is sufliciently wide to permit insertion of the lower end of a blade into the recess 1 so that it can be pushed down between plates 6 and II] to abut against the abutment 9. The blade is held from upward movement by the upper edge of recess 1. A grip I8 is affixed to plate 6 by bolts Hi.

I provide means, both horizontal and vertical, to guide the cutter which consist of a horizontal plate H to bear on the back of the fabric being cut and a downwardly projecting vertical plate 66, which is a downward extension of the plate 6 to bear against one of the cut edges of the fabric.

The plate I! has a vertical flange l6 which is fixed, as by welding, to the lower part of plate 6. The plate I! extends from the cutting edge of the blade to the rear of plate 6. The top of the forward part of the flange l6 abuts the lower edge of plate III. In operation the underside of plate I! rests on the back of the carpet being cut to support the cutter and to control the depth of the cut. The portion of the blade extending below the plate I! is sufficient to cut through the back of the fabric without projecting into the pile of the fabric to an appreciable degree.

The plate 66 extends below plate l1, Fig. 2 and is in alignment with the cutting blade. The plate 66 follows the blade through the fabric as it is being cut and bears against one side of the cut fabric so that it acts as a lateral guide for the cutter. The vertical plate 66 and the horizontal plate ll form a right angle, 66 riding against a cut edge and H riding on the back of the fabric, so that the operator is enabled to make a quick cut of a definite limited depth while keeping the cutter in a straight line. The forward part of plate 66 and the forward part of the flange l6 laterally form a support close to that portion I4 of the blade 13 which extends below plate Ill.

In operation the operator pushes the cutter forward while maintaining the vertical plate 66 and the horizontal plate l1 against a cut edge and the surface of the back of the fabric respectively so that the cutter does not deviate from its course. As a result, the back of the pile fabric may be cut accurately and rapidly to the predetermined depth.

I claim:

A. fabric cutter for cutting the back of a pile fabric comprising a cutting blade, a main vertical plate having a recess therein to receive said cutting blade and having a portion extending into said recess at its bottom and forming an abutment to support said cutting blade, said main plate having a portion extending forwardly of said abutment, said forwardly extending portion having a bottom surface in a horizontal plane above said abutment to ride on the back of the fabric being cut, means to guide the cutter vertically consisting of a horizontal plate secured to and extending laterally from. the lower portion of said main plate and extending rearwardly from said recess, the bottom surface of said hori zontal plate being in the same horizontal plane as the bottom surface of the forwardly extending portion of said main plate, means to guide the cutter horizontally consisting of a portion. of said main plate extending rearwardly of said abutment and having its lower edge below the bottom of the forwardly extending portion of said main plate, and a second vertical plate attached to said main plate and partially covering the recess in said plate, a portion of said second vertical plate extending forwardly of said recess wholly above the bottom surface of the forwardly extending portion of the main plate, whereby the portions of the horizontal plate and the main plate to the rear of the recess guide the cutter both vertically and laterally.
